Solution
Substitution in mathematics refers to the replacement of a variable in an equation with a specific value. This is often done to solve the equation or to simplify the expression. It's not about convincing someone else to do your homework, and it doesn't involve rewriting the equation to remove variables. Instead, it's a method used to make solving equations more manageable. For example, if you have the equation x + 5 = 10 and you know that x equals 5, you can substitute 5 in place of x to confirm that the equation is true (5 + 5 does indeed equal 10).
